This is the main truck side harness for a Curtis snow plow. This is the control harness, the power cable and battery wire. You still need two things: the solenoid and the truck specific headlight adapters - parts we also sell. This kit is CST1UH. This is the newer 2-plug wiring harness. Curtis no longer sells the 1 piece plug. They separated the power because they were going bad. So if you are converting it over, you will also need the plow side 1UHP.
